Audiogrep is a python script that transcribes audio files and then creates audio “supercuts” based on search phrases. It uses CMU Pocketsphinx for speech-to-text, and pydub to splice audio segments together.

This is a sister project to my videogrep script, which does a similar thing but with video (and makes use of subtitle tracks rather than speech-to-text).

So far I’ve mostly been experimenting with audio books. Here, for example, are all the phrases in How Google Works by Eric Schmidt and Jonathan Rosenberg that contain the word “data”.

And here are all the references to “private wealth” in Capital in the Twenty-first Century by Thomas Piketty:

You can also extract just individual words, rather than phrases.

For example, here are all instances of “money” and “people” from the book The Automatic Millionaire: A Powerful One-Step Plan to Live and Finish Rich by David Bach:

“Control”, “psychological”, “behavior” and “situations” from the nightmarishly titled Get Anyone to Do Anything: Never Feel Powerless Again — With Psychological Secrets to Control and Influence Every Situation by David J. Lieberman

And here’s “relax”, and “large” from Breast Enlargement Hypnosis, a truly remarkable audio experience by Victoria Gallagher.

Another experiment from the same amazing source:

It’s also possible to use the script to create “frankenstein” sentences. Here’s Bill Clinton telling us to stop voting, sourced from his book My Life:
[soundcloud url=”https://api.soundcloud.com/tracks/192352609″ params=”color=ff5500&auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false” width=”100%” height=”166″ iframe=”true” /]

And, by integrating moviepy, you can generate video slideshows like these or this:

The code is available on github. Next up I’ll be integrating some of this functionality into videogrep for more refined searches.
